With these the Spring 19 50,

and other objects not specifically mentioned in The cigar bands B are Stacked vertically in a view, the invention consists in certain construcband magazine20 having opposed end walls entions and combinations which will be hereinafter gaging the ends o f the bands in the stack. i At the fully described and then particularly pointed out lower ends of these walls are provided wedgingv in the claims hereunto appended.`

elements or ledges 21 which serve to support the 5 54 bands in the stack. These elements 21 have inwardly and downwardly inclined wedging surfaces extending from the end walls 20 at an angle of less than forty-five degrees to the vertical end Walls. The inclined surfaces of elements 21 serve to produce an endwise pressure on opposite ends of the lower bands and thus to arch the bands outwardly and downwardly from the stack to separate the central portions of the band. l

The bands are withdrawn from the magazine one by one by suction arms 22 on a rotating turret 23 which has a vertical band removing movement and a rotary conveying movement produced yby means which will now be described.

The turret is carried by a shaft 24 `and driven v step by step through gears 25, 26, 27 and 28 by a Geneva wheel 29 actuated by roller 30 on gear 31 driven from the main drive of the machine through spiral gears 32 and shaft 33. The turret as a whole is given its vertical movement as more fully disclosed in the above mentioned application, by a cam lever 34 mounted .onshaft 35 and controlled by a cam roller 36 operated by a suitable cam on shaft 37.

The band B is folded about the cigar C by folders 38 supported on arms 39, pivoted on stud 40 secured to slide 41 which imparts vertical movement to the folders through the levers 39 to fold the band along the opposite' vertical sides of the cigar. The slide 41 is given vertical movement by a link 42 connected to a lever 43 pivoted on shaft 44 and carrying a roller 45 engaging a cam on shaft 37. The lowermost position of the slide and the band folding parts carried thereby is indicated by dotted lines in Fig. 1.

v For the purpose of moistening the band B, there is provided a moistening element 46 in the form of a small roller of yielding moisture absorbing material such as felt, rotatablymounted on a reduced end portion of a carrier bar 47 having reciprocating .end-wise motion on a bracket 48 slidably mounted on guide rods 49,'the reciprocating movement being derived from a bell crank lever 50, pivoted on shaft 37 and actuated by a lever 51 pivoted at 52 and carrying a roller 53 Yengaging with a cam on shaft 37, said lever 51 being linked by a link 53 with the bell crank lever vr50 which in turn is connected by a link 54 to the bracket 48.

For the purpose of preventing rubbing of the roller 46 as it passes the liquid supply device now to be described, a moistening wheel 55 supported in a reservoir 56 driven by a shaft 57 is provided which is given a movement toward and away from the path of the bar 47 by a cam 58 resting on a stationary surface 59. The shaft 57 is driven through gears 60 and 61 and a chain 62 from the drive shaft 37. The moistening wheel has its peripheral portion covered with a suitable yielding moisture absorbent material such as felt. The timing of cam 59 is such that the moisture supplying wheel 55 is moved into contact with the moistener roller 46 after the roller has been moved alongside the surface of the wheel 55.

' For the purpose of yieldingly pressing the moisture applying element 46 against the band B and also for the purpose of permitting it to yieldingly follow the contour of the folder 38 while squeezing the band against the same, as shown in Fig. 2, the bar 47 is pivotally mounted by means of pin 63 on the bracket 48 and is resilientlydrawn into band and holder engaging position by a spring 64 anchored to said bar and the bracket 48.

After the band has been folded about three sides of the cigar by the vertical movement of the folders 38, the band ends outstanding are overlapped by folding means including a roller 65, as disclosed in the above mentioned application, which roller is given movement across the lower side of the cigar in a directionparallel to the direction of cigar movement on the conveyor 11. The folded roller is given this movement by a rack 66 slidably supported by means not shown and actuated by a gear segment 67 engaging teeth on said rack, the gear segment receiving movement from a shaft 68 connected with the main drive of the machine. At the next station of the cigar on the conveyor shown at the right, Fig. 2, there is provided a boss 69 on a plate 70 which serves to maintain sealing pressure on the cigar. At the edge of the plate nearest the banding station a bevelled slot 71 is provided for receiving the roller at which point the roller is withdrawn from contact with the cigar, thus maintaining sealing pressure on the cigar overlap from the banding station to the next station.

In the operation of the improved banding mechanism the moistening or liquid applying element 46, after receiving moisture from the supply wheel 55 reciprocates to a position underlying the band end at the position in which the band extending straight is clamped between the turret arm 22 and the cigar but spaced below said band end. As the folders 38` move downwardly transversely of the vertical sides of the cigar to lay the band in U formation about the same, the band is forced into contact with the band moistening element and during the continued movement of the folders 38, the curved rear surface 72 `of the folder 38 swings the folder away from the cigar against the action of spring 64 and drags the band over said roller which due to its rotatable mounting is in rolling Contact with the band. It is noted that since the band is clamped against the cigar and partially wrapped around the same prior to moistening, there is no chance for the band to be displaced by the engagement of the moistening element with the band. It is also noted that due to the location and movement of the moistening mechanism to the rear of and below the turret, the operator of the machine who is ordinarily to the left of the machine as shown in Fig. 1, has easy access to the band applying elements and to the cigar.
